Operation eBook Drop
This group of authors offers their eBook titles for free to deployed members of the coalition armed forces. I joined because I come from a long line of members of the armed services, and it's my small way of thanking those who currently serve.
So if you are a member of the military who is deployed, go sign up. There are over 1360 authors giving their books away for free. And if you are an author with eFormat titles, consider joining.
